rich progress bars

[v1gnesh]

Hello,

Firstly, thank you for sharing your work through this project.
I can forget about dask entirely, thanks to vaex.

If you have time, could you please show me/us how to do nested progress bars (#1738 and #1771) with rich.
I'm looking to add progress bars to some asyncio + aiohttp code, creating task lists and then *gather to execute them.
Example:

tasklist1 = get_main_objects()
main_objects_json_out = asyncio.gather(*tasklist1)
tasklist2 = get_child_objects()
child_objects_json_out = asyncio.gather(*tasklist2)
tasklist3 = get_child_objects_props()
child_objects_props_json_out = asyncio.gather(*tasklist3)

Tasks in all lists can run as and when they can, I'm just doing list1, list2, then list3 now as I haven't gotten to chaining them together yet.

Sorry, I know it's not directly vaex related but since you've worked on this use case already, any guidance you can give will be very helpful.

Thank you!
